For this reason, in the production process, the enterprise needs to test the chemical composition of the product in order to distinguish the steel and improve the production process.

At present, there are two main methods for determining the content of carbon, manganese and sulfur in iron and steel: one is the chemical analysis method, which has high accuracy, low requirements for samples, and a wide range of determination, and is mostly used as an arbitration method. The sample preparation method is cumbersome, the analysis process is complicated, the analysis time is long, and the test personnel need to have strong theoretical knowledge and hands-on ability; the second type is the instrument analysis method, which has the advantages of fast analysis speed and simultaneous determination of multiple chemical elements in steel. content, high accuracy, easy operation, low detection limit, and easy operation by personnel, etc., but this method has limitations on the size of the test sample and the test range of the control sample standard steel, such as the SPECTROLAB M10 photoelectric sensor imported from Germany by our company Due to the limitation of the excitation groove diameter of the spark table, the direct reading spectrometer can test the samples of rod samples or block samples with a specification greater than 13mm.
